Just Intonation is an infinite universe. A justly-intoned pentatonic can be very effective in the hands of a sensitive composer, and in this electronic age that same composer on another day can use a scale with hundreds of notes in an octave. One approach to making just intonation not only practical but easy is to map an [[Periodic scale|octave-repeating]] 12-tone JI scale to a standard keyboard. This page collects some of these scales, and a [[Gallery of 12-tone Tempered Scales|companion page]] does the same for tempered scales. * [[otones12-24|otones 12-24]] a.k.a.
